How to fix BLE devices #12

AuroraWright · 2018-07-30T08:23:20Z

I just made my BLE MS Designer mouse work on both Windows and macOS.
Steps are as follows:

Pair on macOS first, and then on Windows.
Export HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BTHPORT\Parameters\Keys\{bluetooth adapter MAC}\{BLE device MAC} to a reg file and reboot into macOS.
Disable Bluetooth.
Modify /Library/Preferences/com.apple.Bluetooth.plist replacing all instances of the previous MAC address of the BLE device with the new one, and also modify /private/var/root/Library/Preferences/blued.plist (up to Sierra) or /private/var/root/Library/Preferences/com.apple.Bluetooth.plist (High Sierra onwards) as follows:
-- Expand SMPDistributionKeys, and expand again the dictionary named after the bluetooth adapter MAC, you'll find one sub-dictionary for each BLE device, named after their MACs. Replace the MAC of the device you're dealing with with the new one, and expand that dictionary.
-- LTK, RAND, IRK, address and EDIV need to be changed. They're respectively LTK, ERand, IRK, Address and EDIV from the reg file, nothing needs to be endian swapped except for the EDIV (as an example, "EDIV"=dword:000080b4 in the reg file means the macOS EDIV is b480) and the Address (as an example, "Address"=hex(b):46,78,f9,ba,1a,db,00,00 in the reg file means the macOS Address is db1abaf9 7846).
Save the files and reboot, re-enable Bluetooth.

Thank you very much for your solution.
I've followed your steps but failed.
I'm using win10 1809 & macOS 10.14.2 mojave.
My BT device is Logitech M585 Bluetooth4.0 BLE which requires CSRK value under win10.
Following the steps, after modified Bluetooth.plist and bluetoothd.plist ，reboot .
the mouse automaticly link to macOS ,but the EDIV LTK RAND value in bluetoothd.plist changed.
It lose connection with win10.
Did you encounter with this problem?
Any suggestion?
Thank u!

AuroraWright · 2018-12-09T16:27:35Z

No, that never happened to me. I also recently got ahold of a Microsoft Designer Keyboard (which is also BLE) and it works fine on that too. CSRK is useless basically, it's only used during the initial key generation process, no idea why Microsoft keeps it in the registry (if you edit it to all zeros it still works).

foxevereg · 2018-12-10T04:55:53Z

Thank u so much for ur reply.
it seems when macos links to the mouse, it does a pair action, changes the values in bluetoothd.plist.

i've tried to fill the values to win registry but the mouse was still not working.
it connected to win, and disconnected after a short while. connet and disconnect.

i'will look for other bluetooth 4.0 mouse to do a test. Maybe it's device variant.

foxevereg · 2018-12-12T00:57:50Z

CSRK is useless basically, it's only used during the initial key generation process, no idea why Microsoft keeps it in the registry (if you edit it to all zeros it still works).

I managed to find a Mictosoft Designer mouse and modified the plists, then rebooted. The values changed all the same.
How about your macOS version? And how did you modify the plists, PlistEdit Pro or just command line?

AuroraWright · 2018-12-12T09:17:17Z

I first disable bluetooth on macOS before replacing the plists. Then I use the command line (with sudo) to copy the plists somewhere else, make them accessible by myself, and use the XCode built-in plist editor. I then change the permissions back to those of the originals and copy them back, then reboot. I finally re-enable bluetooth. This works on both Sierra and High Sierra. I doubt anything changed on Mojave.

foxevereg · 2018-12-13T01:05:26Z

Disabling bluetooth is the KEY STEP.
Disable bluetooth, then replace the plists, the values will not change.My mouse works fine under both macOS and win10 now.
Thank u so much for your detail steps!

foxevereg · 2018-12-13T04:11:04Z

i've posted the full steps on a hackintosh forum to help more people.
Have a look at the acknowledgments list:)

AuroraWright · 2018-12-16T15:29:45Z

Thanks for the acknowledgement, I also clarified that Bluetooth should be disabled and then enabled again in the first post

filipnavara · 2018-12-23T00:25:40Z

Just a heads-up. After upgrading to Windows 10 build 18298 the keys were actually moved somewhere else in the registry. The old values before the update could still be found at "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BTHPORT\Upgrade\BTHPORT\Keys" (note the Upgrade part), but for newly paired devices you are out of luck.

AuroraWright · 2018-12-23T00:46:35Z

Did you try looking for the new location?

filipnavara · 2018-12-23T00:49:35Z

~~I did, there's new "FingerprintString" in the "Devices" key, but I didn't really see an obvious mapping between the two. It's possible they are unrelated.~~

AuroraWright · 2018-12-23T00:51:32Z

I'd try looking for the mac addresses of the devices or something like that... if nothing shows up, maybe they're in the filesystem now

filipnavara · 2018-12-23T01:11:33Z

Turns out I was probably wrong. I re-paired the mouse and re-run regedit under PSExec and there are new values in the Keys... I guess I must have done something wrong the first time.

UPDATE: And it indeed works! Thanks!

AuroraWright · 2019-01-02T16:35:12Z

@foxevereg You don't need to endian-swap the IRK as far as I know. Both my Designer mouse and my Designer keyboard work without swapping it (and I think it doesn't make sense that Apple would have IRK and LTK with different endianness).

foxevereg · 2019-01-05T02:17:36Z

I think it doesn't make sense that Apple would have IRK and LTK with different endianness too.
I was also confused with the fact.
When I was trying to connect my mouse to both win10 and macOS.
It was found that IRK won't change after repairing my mouse.
when paired under Win10, the IRK is hex:76,d9,aa,05,2d,3b,db,e7,40,9d,59,a7,f9,94,f0,72(in exported reg file)
when paired under macOS, the IRK is <72f094f9 a7599d40 e7db3b2d 05aad976>
so, I make endian-swap to IRK.

It seems either endianness will work under macOS?

pwiatrowski · 2019-06-11T14:31:20Z

it's been a while since the last update to this post but I didn't want to open a new case so let's write here.
I followed the procedure described here and successfully dual-paired the Microsoft Mobile Mouse 3600 - thanks for that!

However, I've got a big issue with the Microsoft Modern keyboard - I cannot get it to work :(
I tried multiple options but no joy - the problem is that I cannot pair it at all in macos as it requires connecting via USB for the initial pairing in Windows. I did that and tried to transfer the keys and create manual entries in /Library/Preferences/com.apple.Bluetooth.plist but I get nowhere.
I feel I'm missing correct settings in DeviceCache section - is that correct assumption?

Does anyone have any ideas what I can try to make it work?
I found that someone did exactly that on Linux (https://askubuntu.com/a/1063285) but Linux has a different syntax of the Bluetooth config files (especially the 'Services' section).

Any help is more than welcome!

Cheers!

someperson · 2019-06-25T04:38:59Z

I have a device that shows up as BLE in macOS, but Classic Bluetooth in Windows. What can I do to make this somehow work? The device is a Bose QuietComfort 35 II, and in Windows, it actually shows up in the pairing list as two devices, one of which is BLE and does absolutely nothing, the other of which is Classic Bluetooth and works. macOS, on the other hand, only seems to want to connect to it using BLE, which works. Is it possible to somehow disable BLE in macOS temporarily so I can get it paired to both systems using the same method?

Anyone has any tip for the above case? I would love to use my Microsoft Modern Keyboard on macOS without the USB cable, but that seems impossible. =/

Howdy, I have Microsoft Modern Mobile Mouse (it's next step evolution Microsoft Designer Mouse), after paring, OS (Windows 10 and Hight Sierra) not created IRK and Address Fields in *.plist and Reg, who fighting with this trouble?

It is empty after 20H2 upgrade.

It is empty after 20H2 upgrade.

it is not empty
you have no access rights to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BTHPORT
make yourself an owner

macmeister1967 · 2021-05-09T02:25:56Z

@roddy20 , how do I do that exactly?

borodaxel · 2021-05-09T08:29:35Z

It is empty after 20H2 upgrade.

Sorry. You need to run regedit with pstool (official from MS) to get rights of SYSTEM user. Then you will see contents of BTHPORT section.

macmeister1967 · 2021-05-10T01:31:08Z

many thanks, I'll give it a try on my desktop PC first :-)

Is this normal that this method doesn't work in Monterey?

/Library/Preferences/com.apple.Bluetooth.plist looks like this (as expected, I suppose)

However, there is no com.apple.Bluetooth.plist in /private/var/root/Library/Preferences.

I am aware the bluetooth stack was rewritten in Monterey, so I am guessing the file which has the necessary keys has changed. Does anyone have any info about this?

whatnameisit · 2021-12-05T14:29:50Z

/Library/Preferences/com.apple.Bluetooth.plist looks like this (as expected, I suppose)

That's probably a residual file from previous OS. After fresh installing macOS Monterey, I have no such file with multiple BT devices connected. BCM94360NG.
The creator of Hackintool has come up with a fix for porting keys of generic(?) BT devices in Monterey:
benbaker76/Hackintool@6398a4b
benbaker76/Hackintool@c12446d
and I have connected Logitech K380 keyboard on both macOS and Windows with a single profile.
But as of now, the tool has never supported porting keys of BLE devices, and I have no idea what's going on in the source code.
@headkaze, would it be possible for you to give us any information?

benbaker76 · 2021-12-06T19:04:47Z

@whatnameisit you can view this post on Reddit for manual instructions.

whatnameisit · 2021-12-08T12:52:39Z

@whatnameisit you can view this post on Reddit for manual instructions.

Thanks, headkaze. I am now able to use BLE devices on macOS and Windows with single profiles!
For anyone if they would like to know, I edited four properties:

EDIV:modify
IRK:modify
LTK:copy
RAND:copy

I'd be interested in adding support for these 4 additional attributes to Hackintool. Can you please post the output to the following commands (as well as your final working Windows .reg file).

security find-generic-password -s MobileBluetooth -w
system_profiler SPBluetoothDataType -xml

whatnameisit · 2021-12-09T02:08:19Z

@headkaze, I don't think the first command would do anything meaningful because BLE devices have their own respective "key" like below:

I used the above key to extract relevant information.
If you still need them, here is the output.

1.txt
2.txt

Windows .reg file 8863df8a2d80.zip

I double-clicked the BLE device with familiar "Account"; clicked "Show Password" as stated in the reddit post; 3.txt found four attributes Encrypted Diversifier(EDIV), Long-term Key(LTK), Random Number(RAND), and Remote IRK(IRK); endian swapped EDIV and IRK; copied swapped EDIV, LTK, RAND, and swapped IRK over to Windows; and pasted them in Windows regedit accordingly. IRK was pasted in two respective places which I will show later.
IRK once here:

and again with other keys marked with blue lines:

I noticed the "Account" name in Keychain Access is the same as the "Address" in Windows regedit in red.

benbaker76 · 2021-12-09T05:56:22Z

Thanks @whatnameisit. I've pretty much got it implemented in Hackintool.

Can you please try the attached version and see if it will generate a matching reg file.

whatnameisit · 2021-12-09T10:21:13Z

@headkaze Hackintool has managed to generate reg keys for devices other than the very device I'm using right now. Honestly, I have no idea what devices those keys are for because I only have one BLE mouse. Keychain through Apple account copied from previous BLE devices which I don't know of, maybe?

Bluetooth.reg.zip

One other thing I noticed is that the "Account" name of those two is "Public xx:xx:xx:xx:xx:xx" whereas that for the actual device I'm using is "Random xx:xx:xx:xx:xx:xx".

If you know anything about them, I'm pretty sure you will have everything sorted. If you don't, please let me know and I may do a fresh installation of macOS 12 and do the test before logging into Apple ID.

benbaker76 · 2021-12-09T14:47:06Z

@whatnameisit yes those devices you're seeing are old BT devices you've connected to in the past. You don't need to do a fresh installation you can safely delete them from the keychain.

I have two devices connected and one has a Public and the other has a Random entry. The Public version has no Remote Encryption->Random Number entry whereas Random does.

First issue I'm seeing is the "MasterIRK" value will be overwritten with each device so there must be some other way to deal with this.

Second issue is the file you sent me only has a "Remote Encryption" entry but mine also contain "Local Encryption->Encrypted Diversifier" entries. These could in fact be another layer of encryption. What version of macOS do you have? Mine is macOS Monterey 12.1 Beta (21C5031d)

I've also added the following entries manually although I'm not sure what they mean or what they relate to.

"AddressType"=dword:00000001
"MasterIRKStatus"=dword:00000001
"AuthReq"=dword:0000002d

Please try the attached version and see if you can get two BT devices (preferably with Public and Random entries) working. What happens if you remove the "MasterIRK" entry?

whatnameisit · 2021-12-10T12:59:53Z

My OS version is 12.0.1(21A559). I only have one Random BLE device, so I can't test with Public BLE device.
The newly attached version recognized my Random BLE mouse. It did not reverse the ERand or EDIV though.
Hackintool generated: Bluetooth.reg.zip
Windows exported: 8863df8a2d80.zip

I deleted "MasterIRK" entry yet the mouse is still working after reboot: bluetooth.zip

I've just done a release of Hackintool with ERand and EDIV reversed and removed "MasterIRK". Can you please give it a try and let me know if it looks correct to you.

whatnameisit · 2021-12-11T00:33:33Z

Yes, it's working all right! Thank you for your work :)

@headkaze, I don't think the first command would do anything meaningful because BLE devices have their own respective "key" like below: I used the above key to extract relevant information. If you still need them, here is the output.

1.txt

2.txt

Windows .reg file 8863df8a2d80.zip

I double-clicked the BLE device with familiar "Account"; clicked "Show Password" as stated in the reddit post; 3.txt found four attributes Encrypted Diversifier(EDIV), Long-term Key(LTK), Random Number(RAND), and Remote IRK(IRK); endian swapped EDIV and IRK; copied swapped EDIV, LTK, RAND, and swapped IRK over to Windows; and pasted them in Windows regedit accordingly. IRK was pasted in two respective places which I will show later. IRK once here: and again with other keys marked with blue lines: I noticed the "Account" name in Keychain Access is the same as the "Address" in Windows regedit in red.

Sorry if this is a silly question, but how did you convert the format of the values from 3.txt into the correct format for the registry? Following the reddit post I was able to get an output in the same format as yours, but I can't copy paste the values as they aren't hexadecimals
Key.txt

You can use Hackintool to generate the Windows registry file (it's in the Tools tab)

I tried that, but after importing, I found my headphones had started working, but not my mouse, so I tried looking at the generated reg file and comparing addresses there appeared to be no entry for the mouse at all, and so using Keychain Access I noticed that only the headphones had a "MobileBluetooth" entry, while the mouse had an entry similar to above.

``Monterey has changed bluetooth architecture.
Chanzong write a blog of synchronizing bluetooth between Monterey and Windows in Chinese.
https://zhuanlan.zhihu.com/p/483454678

headkaze's hackintool can export windows reg files.
My mouse works fine both macOS and win11. Export reg file with bluetooth devices disconnected.
it's the first choice to sync BLE device between windows and mac.

But keyboard does not work, there is both Local Encryption key and Remote Encryption key in macOS keychain xml.
I tried to replace EDVI and ERand in reg file with the value in Local Encryption key. It did not work.

Keyboard still works after deleting Local Encryption keys. It seems Local Encryption does not affect BLE device connection.

20220411update:
After replacing all old MAC address with new MAC address in all the keys and values of windows registry。
BLE keyborad gets to work。

Hi. Hope anyone can help me.
Im pairing my combo ( keyboard and mouse ) device on monterey and win 11. This is Bluetooth LE device
Here is my device. Its rii i4 : http://www.riitek.com/product/i4.html
I found some problem
i can pair magic mouse of both, but can not connect i4 on mac os. When my friend connect his airpod on my mac os, then i can connect my i4, when he disconnect his airpod, i still can connect and use my i4. And when i remove his airpod profile, i will lose connect of i4. I though this problem like my i4 need something from airpod profile, then i4 can connect and use

about pair my i4 with monterey and win 11.
I tried get information from xml source of keychain access ( ediv, ltk, rand, irk ). Then edit registry on windows with that information. It did not work

Tried use hackintool 3.8.7 for get bluetooth reg. And i can see this reg file make 2 new keys on registry (cc088d04f4b6 and dca4cad9aea4). But that key not correct with MAC address. Test it and it did not work too

help help help … sos sos

my i4 mac address : 72000012373e

@lilce083
it seems i4 has 2.4G usb dongle，since you are running a real mac.
why not try 2.4G usb dongle.

lilce083 · 2022-04-21T17:02:21Z

Pair is complete. Just do it step by step with tutorial from china and hackintool 3.8.7

Connect to windows
Connect to monterey
Disconnect from monterey ( keep profile on bluetooth pres ). This step make me can export bluetooth reg file from hackintool with my ble device ( rii i4). If i dont disconnect, i cant export reg file have my device
Generate reg file by hackintool
Import to windows
Restart and bingo
Tks all

I am unable to see any Keys under

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BTHPORT\Parameters\Keys

I ran PsExec -i RegEdit (had to create a shortcut since I have to run it as Admni) and I still see no keys. What am I doing wrong?

Thanks

In my Intel AC9560, I (re)installed bluetooth drivers after I didn't see any entries in the registry. Afterwards, I merged the keys and it has worked ever since.

Thanks, I just tried that. I removed the Intel Bluetooth driver, rebooted.. still nothing. When you say 'merged the keys".. is there another step I need to do to see them?

Just the default key.

I use BUFFALO BSMBB09DS to test the success steps as follows

WIN 10 pairing is completed and confirmed to be available
macOS Monterey re-pairing confirmation can be used
BUFFALO BSMBB09DS power off
Use Hackintool to export the Bluetooth configuration file name Bluetooth.reg
Reboot to enter WIN 10
Modify Bluetooth.reg
Change "AddressType"=dword:00000001 to "AddressType"=dword:00000000
Save the new file Bluetooth_FIX.reg
Use PSTools PsExec.exe to import BluetoothFix.reg
10 Reboot and test OK

Hackintool does nothing for my devices, and I cannot access the guide mentioned here.

Still looking for BLE support between macOS and Windows.
